To LZ-Z whom, it may concern: a

Be it known that I, JOHN ANDREW GRlMM,

a citizen of the United States, residing at the borough of Manhattan, in the city, county, and State of New York, have invented a new and useful Improvement in Machines for Shelling Nuts, of which the following is a specification.

My invention relates to a power-operated automatic machine for severing the `shells of nuts by scoring or incising for the ready removal of the meat.

In carrying out nly invention the nutsare placed in a hopper and are agitated to cause the same to pass endwise into holes in the hopper-bottom. vFrom these holes the nuts pass one at a time into coinciding holes of a carrier-disk placed below the hopper-bottoni, and for this purpose the carrier-disk and hopper-bottom are sim ultaneousl y rotated. Vertically-moving linger-bars engage one nut at a time and push the same out of a hole iu the carrier-disk and down through a coinciding hole in an auxiliary bed and then between a series of radially-placed pairs of revolving circular saws nlounted on springactuated supports, and which saws sever the shell by scoring or incising the same lengthwise from point to point. The finger-bars are positively actuated, yielding, and adjustable, and suitable devices are employed for progressively operating the various parts for feeding the nuts, operating the circular saws, and removing the nuts from the finger-bars, after which the shells and meat may be separated by hand. All of these devices are hereinafter more particularly set forth.

. In the drawings, Figure 1 is a plan view representing my improvement. Fig. 2 is a partial elevation and longitudinal section. Fig. 3 is a plan View representing the carrier-disk and a part ofthe hopper-bottom with the holes for the nuts and the means for rotating the same. Fig. 4 is a plan of the disk below the hopper-bottom. Fig. 5 is a plan ofthe auxiliary bed through which the nuts pass. Fig. .6 is a cross-section of the same at x. Fig. 7 is a plan of the first auxiliary bed and the circular saws and means for operating the same. Fig. 8 is a partial section and elevation of two saw devices of Fig. 7. Fig. 9 is a cross-section through the main and the first auxiliary bed and a section ot' the linger-bars'. Fig. 10 is a partial c ross-section and elevation at y y of Fig. 1. Fig. 11 is a cross-section of a shaft and elevation of the cam for imparting motion to the hopper and carrier-disk. Fig. 12 is a plan and partial section of the modification of the parts shown in Fig. 7, and Fig. 13 is a View showing the saws and gagebars on a larger scale. l

The main bed a is provided with suitable supporting-legs ct', and on oneend of the main bed I provide an auxiliary open-center bed b and screws b for holding the bed b to the main bed. Above the auxiliary bed b is a second auxiliary bed c, secured by screws C', passing through holes 14 in projections from the under side of the said bed c to the auxiliary bed Z9. The supporting-legs of the main frame are preferably connected by tie-rods 1, and upon and connected to the upper and lower surface of the main bedv are bracketbearings 2, 3, 4, and 5 forthe parts hereinafter described. I also employ bracket-bearings 6 and 7, there being several of the bracket-bearings 6. from the main bed a, and another post 9 from the auxiliary bed b,the lower free ends of which posts are connected by a strap 10, and a series of pulleys d is pivotally connected to the brackets 6. sliding adjustable bearing is connected to the post 8, and a pulley d2 is connected to the bracket 7. I provide a post e, connected by a stem and nut at the lower end of the auxiliary bed c and rising therefrom, and a notched disk e' is secured to the post.

The hopper-bottom f is a perforated diskthat is to say, there is a series of similarlyspaced-apart holes at the same distance from the center of the disk or hopper-bottom-and the edge is made with teeth. This will be apparent from Figs. 1, 2, and 3 of the drawings. The hopper f is of sheet metal connected to the bottom fand flaring. Within the hopper surrounding and connected to the post e is a guide-sleeve g, to which is connected a coverplate g', the position of which is fixed and which is of suicient area to close over one hole of the hopper-.bottom at a time. `Astirrer-rod g2 is connected to the guide-sleeve g, said stirrer-rod havingvan arm or end passing down toward the llopper-bottom and inclined I further employ a depending post S A pulley d upon a IOS thereof. The nuts, which, by preference, arev pecan-nuts, are placed loosely in the hopper, and the lowermost nuts are free to pass into alll of the holes except the one covered by the plate g. They are assisted in passinginto the holes by the stirrer g2 as the hopper revolves.

A post 11, of angular cross-section, is connected to and rises straight up from the auX- l iiiary-` bed b, the oice of which will be hereina'fter `described. A center pin 13 screws into the auxiliary bed c, and surroundin g this Center pin` is a perforated carrier-disk h, also provided with edge teeth, as will be seen from Figs. 1, 2, and 3. Surrounding this carrierdisk andtting an angular recess in its periphery isa guide-ring vl, having a projection atene side to which the pawls t" t2 are pivoted. These; pawls are spring held or actuated, one resting, against the periphery of the hopperbottom fand the other again-st the periphery @E the carrier-disk h, and a connecting-rod 7c' isatoneend also'pivoted to the projection from the said guide-ring t', the reciprocation of which connecting-rod, together with the forward-and-backward swinging movement et" thegu-idening, causes the pawls '2 to engage the teeth of the hopper-bottom and the carrier-disk, so-that the said parts are sim-ultanedu'sliy turned, one tooth at a time, in the same direc-tion, so as to permit one hole of the hopper-bottom f and one hole of the carrie-redislr h to vertically coincide, as shown in Ii'g., 2", with eachmofve-I-nent of the said parts, .so-that asv a nut in a hole of the hopper-bottom-` comesfu-nde-r the cover-plate g' it is frerey tetiall from the hopper-bottom into the car-l rier-dish, andv in this manner the nuts are Y transferred onel at a time from the holes in ther-operation o-t the; parts to be hereinafter die-scribed'. l

The auxiliary bed c at the center hole 15 is 'radially slotted for spring-actuated hars Z, (see Figs. 5l and 6,) which bars' are held in plaeeb'y a retaining-plate Z on tl're u nd-er side Y on the auxiliary bed b.

o-F'the' said bed. A series of double-radial (rirenlarl saws m are mounted upon shafts passing through sleeves m', and the said' sleeves/rrr' are mounted' upon pivot-posts in2 and 7.)= vThe shafts of the saws yare each provided with a pulley 1G onthe-oppositegend and'bycwhich the shaftsand sawsarerotatedj. Between ea'clipair of radial' circular sawsA I (See specialfliy Figs. i

place a gage-bar 17, and each sleeve m is provided with a supporting-head 18, connected thereto by a bracket. On the free end of each head 18 is an adjusting-screw 19, and the back end ofcach gage-bar is mortised, as shown at 48, Figs. 8 and 13, to receive part of a rib on said adjusting-screw 19, the said gage having ways provided therefor by proy. jections of the head on the opposite edges of the said gage-bar and said gage-bar being slotted for a screw passing through the same into the head, which parts are shown clearly fin Figs. 7 and S, the said projections, slot, and screw permitting the gage-bar to move longitudinally with the rotation of the adg justing-screwV 19. I

The portion of the gage-bar between the i circular saws is of hook shape, the outer-edge lxthereof on a horizontal plane being more distant from the center ofthe circulars-aws than the adjacent portions above and below the same and which portions are with reference to the center of the circular saw at about angles of forty-five degrees. This construction of the curved end of the said gageeb'arprovides for less of the teeth at the horizontal center being available than are available above and below the said points, and I employ springs 20, one end of each of which is connected to the bed and the opposite ends to eyes upon the .sleeves m' for ythe purpose of forcing the sleeves and the saws toward the vertical center of the bed l), and I employ stops 2l on the bedb to limit the movement "of the sleeves, so as to prevent the radial cir-V cular saws from coi-ning into actual contact with one another.

A 'sleeve22 surrounds the rising post 1i, and a socket-arm 23 extends out from the socket-arm is a finger-bar n, screw-threaded upon its upper end or stem n/ and provi-ded with nuts 2t upon the opposite sides of thel socket-arm, so as to adjustablycon-nect the said finger-bar n to the said socketarm. They linger-bar n points downward and moves ver- -.ticall'y through the hole in the carrierdis-k and in the auxiliary bed c for the purpose of l' pushing the nuts one at a time out of the'A f said holes to be operated upon by the circular saws, and I provide a finger-baro, pointing upward and moving vertical-ly, which finger-bar is adapted to come partially upl into g operating together to remove the nut and to g hold the same while being operated upon by thesaws, therebein-g sufficient space between 2 the lingersof said bars for the pairs of' cirtion of= the fingers ot' theV bar n with the saws in the openings betwecn'th-e same.v

The finger-bar o has a stem-V passi-ng down' into a. threaded sleeve 0', the threaded sleeve 5219-, there being' nuts 31 upon the, threaded i sleeve o at opposite ends of the socket 30 te passing thro-ugh they soc-liet 30 ot*V tl'resleeve` ICO said sleeve, and passingV through the said i IIO the opening 15 in the bed c to receiveA the l E lower end of they nut, the iin-gerba-rs or and 0 cular saws to operate, Figf' showing a seof jected to its full extent the said finger-bar is capable of a yielding depression to the extent of the slot in its stem, and which movement is controlled by the key, said parts being specially shown in Fig. 2.

The sleeve 29 surrounds the post 9 and is vertically movable thereon, and the sleeve 22 is connected by a link 25 with a rocker-arm 26, pivoted to a shaft passing through the hub 5, on the other end of which shaft is a Weighted arm, (see Figs. 1 and 2,) the rocker-arm, shaft, and weighted arm being connected so as to Work together, the rocker-arm 26 being made with a depending arm 27, carrying a roller, which roller is in the groove of a cam 28 upon the shaft r, in suitable bearings, upon the upper surface of the bed a. The sleeve 29 is connected by a link 32 to a rocker-arm 33, pivoted to the bracket-bearing 4, upon the 'upper end of which is a roller in the groove which is secured upon one sideof the bed a.

This rocker-arm 35 is connected bya universal joint at its upper end to the connectingrod k for actuating the pawls t" 2,and the said rocker-arm 35 carries a roller 37 in the groove of the cam 38, which cam 38 is also upon the shaft r, and there are teeth u upon the periphery of the cam 34, and this cam 34 is provided on one face with a cam projection 42, and pivoted at 40 to the bed a, of the machine is a swinging arm 39, having on one end a roller 41, adapted to come into engagement with the cam projection 42, said swinging arm 39 at its opposite end being enlarged and moving over the surface of the bed, so as to strike the nut after the same has passed through the saws and been released by the removal of the upper finger-bars n. (See Fig. 9.)

The machine is provided with two sources of power, the one for operating the mechanical devices-that is, the finger-bars and the pawls for turning the hopper-bottom and the carrier-disk-and the other power device for rotating the saws. The main power-shaft s is in bearings 3 upon the under side of the bed a. This shaft carries a pinion s', which meshes with the teeth u of thecam 34, said power-shaft s having fast and loose pulleys t, and by these means rotation is imparted to the shaft r to actuate the cams 28, 34, and 38 O ma to cause the operation of the parts heretofore described. The second or auxiliary powershaft c is also mounted in bearings 2 on' the frame cf lthe machine, and on the said powershaft are fast and loose pulleys v. This shaft 'u carries a belt-wheel c2, and the belt passing around the said wheel extends around the Iirst pulley (l, up over one of the pulleys 16, down around the pulley d', up over the second pulley 16, down around the next pulley d, up over the next pulley 16, down around the pulley d2, up over the last pulley 16, down around the last pulley d', and so to the belt- Wheel Q22, the adjustable pulley d being provided for taking up the slack of this operating-belt. In this manner all of the pairs of circular saws are rotated by the same belt at the same speed and the said saws are free to yield upon the pivot-posts m2.

In the operation of the device further than as hereinbefore described each nut to be operated upon in a hole of the carrier-disk h rests upon the spring-bars Z in the bed c, and as the finger-bar n comes against the nut it forces the same through the hole in the carrier-disk down past the spring-bars, righting the nut with the movement, so that it occupies a truly vertical position, the point coming against the upper ends of the finger-bar o.-

As the nut continues the downward movement the saws come in contact with the nut at the lower point, and they cnt through the shell and yield as the nut is forced down, passing over and through the sides and finally through the nut at the upper point, the construction of the gage-bars 17, as hereinbefore described, permitting the circular saws to cut deeper into the nuts at the points than at the sides, the said gage-bar determining the depth of the cut and being set so that the saws will just cut through the shell of the nut without injuring the meat. As the nut passes farther down past the saws the nger-bar n is raised by its operating mechanism, so that the nut rests upon the upper end of the iinger-bar o, which is momentarily held in place by its actuatiug'mechanism. The arm 39 is then swung to knock the nut off the fingerbaro, so that the operations may be repeated.

The action of the pairs of circular saws upon the nut is peculiar-that is to say, there are eight lines of incision or scoring-which cut four sections of shell away from the nut, leaving a slender framework of shell of four portions connecting the. respective ends and serving to temporarily hold the meat of the nut in place, so that thereafter a simpletwist .given by the fingers would be sufficient to sever this framework and free the meat. The movement of the saws is also peculiar, because the swinging movement provides for the saws cutting an incision of greater width than their thickness, so that they free themselves and are not liable to clog or stick in the shell.

In the modification shown in Fig. 12 the saws do not swing, but have a radial yield- IOO IIO

p do not consider this modification as advanf rtf tageous as the devices shown in Figa 7,hecause the .saws acting by a st-raigltaway" yielding motion do not provide the clearance oi' lthe swinging saws.

jI am aware lthat a machine has been here# tofore devised for scoring` or ih cising the shells of nuts, especially cocoa-nuts, by circular saws at opposite points of `the shell that were caused Vte rotate and cut into the shell as the nutwas passed between the saws but in this device the shell was only scored and had to becracked thereafter,- the saws simply facilitating the cracking operation, se that the meat was removed from. the nuts in ai ineres'atisfactory shape than in the oI-d way; butthe deyices of the said maehinefwere te tally different from these employed hy me.
